When motorcycle tyres need replacing

A motorcycle tyre tells you it is finished more honestly than a car tyre, because you can feel the last two millimetres in the way the bike falls into a roundabout. Riders still wait. They wait for the wear bar, or for a nail, or for a mate to say something. Queensland heat shortens the wait whether you like it or not.

The legal idea is the same family as cars: tread, cords, and a tyre that is still a tyre. The practical idea is earlier. A square rear on a sportsbike is a handling problem before it is a legal problem. A front with a felted, shiny strip in the middle is a wet-weather problem on the Captain Cook Bridge.

Wear bars and the shape you can see

Look at the bars in the grooves. Look from behind the rear. If the profile is a plank with two unused sides, you have been commuting in a straight line on a sport tyre. That bike will now need a shove to lean and a prayer to stand up. Replace it. Do not “ride it into the edges”. Those edges are a different, harder, colder compound story after a summer on the ICB.

Front tyres often die from a centre strip and from nicks. A front is cheap compared with the conversation it is having with the road. Replace it when the feel goes vague, not when you can see canvas.

Punctures, cuts and the things you cannot argue with

A nail in the centre of a rear can sometimes be repaired with a proper mushroom from the inside, depending on the maker and the workshop. A sidewall cut cannot. A puncture that has been ridden on until the carcass overheated cannot. If someone offers a string plug in a carpark as a permanent fix, smile and ride slowly to a shop that will bin it. The car puncture rules are harsher on a bike because the backup tyre does not exist.

Age and the weekend bike

A bike that does 1,000 kilometres a year still has a clock. Sidewalls crack. The four-digit week code is on the tyre if you look. A ten-year-old front with “plenty of tread” is a museum piece. Sun on a black tyre at Redcliffe does the rest.

Store spare tyres dark and cool, as the old site said. Do not hang them on a hook that points a bead. Do not leave them standing in a puddle of oil.

Pairing when you replace

A new rear behind a dying front is a classic weave. Replace the front if it is close. Match families. Read sport versus touring if you are using the replacement as an excuse to buy a fantasy. Then book the bike, not the poster.

Riders remember the tyre that saved them. They should also remember the tyre they replaced a week too late. The second memory is more common. Make it someone else’s.

A longer look at the same job

The short version of When motorcycle tyres need replacing is the part you will remember in a fitting bay. The longer version is how that advice survives a Brisbane year: heat in January, a storm in February, a pothole week in March, a highway run at Easter, and a fitter who is busy on a Friday. This desk exists so the longer version still has somewhere to live.

Start with the car you have, not the car in the brochure. Read the door placard. Photograph both sidewalls. Write the pressures down. If you tow, if you run a roof box, if the car is a hybrid with a heavy nose, say those things out loud before anyone quotes a special. A special that ignores load is not a special. It is leftover stock.

How this sits with the rest of the archive

Nothing on Brisbane Tyres is meant to be a lone pamphlet. The car tyres hub still opens the same door the 2007 site opened. Motorcycle tyres still warn you to match front and rear. Tyre suppliers still tell you to test knowledge. Cheap tyres still tell you not to panic-pay, and not to confuse a bargain with a carcass. Care and safety is the weekly habit. Queensland roads is the climate. History is why the brands on a quote have grandparents.

If you are reading this article because a quote confused you, take questions to ask before you buy and how to compare tyre quotes into the bay. If you are reading it because a tyre already failed, take punctures and when to replace. If you are reading it because the sky has gone black, take wet-weather and aquaplaning.

Local details that do not fit a national brochure

Coarse chip-seal on suburban arterials roars a pattern that was quiet on a European press loop. Concrete on the Gateway drones a budget block. Painted crossings after a first rain are ice. A west-facing brick wall in Woolloongabba is an oven. A flooded dip on a hinterland road is not a place to test remaining groove. These are not colourful asides. They are the test conditions.

A fitter who has only worked in a climate-controlled warehouse will still mount a tyre correctly. A fitter who has seen a January week in this city will also ask about the spare, the alignment and the storm. Prefer the second person. Pay them.

What we will not tell you

We will not crown a single “best tyre in Brisbane”. We will not pretend a house brand is secretly a flagship. We will not tell you to ignore the placard because a forum likes a plus-size look. We will not tell you a string plug is a career. We will not tell you a ten-year-old tyre is fine because it has tread. Those sentences sell well. They fail on the road.

We will tell you to measure, to write dates down, to buy the load index you need, and to replace a wet-season tyre before the legal minimum makes the decision. That is a dull kind of editorial courage. It is also the only kind that belongs on a site that started as information on all the different tyres in the market.

A closing habit

Once a month, on a morning the car has sat, check pressures, look at inner shoulders, look for nails, look at the week code if you still do not know it. Once a season, before the first proper storm, measure tread. Once a year, get an alignment printout if the car has hit anything it felt. Those three loops will save more money than a coupon.

If something on this page is wrong for your vehicle, write to the contact desk and name the article. We correct dates and we correct advice. The old site was chatty. We kept the chat and added the duty of care.

A worked example from a ordinary Saturday

Imagine a 2016 medium SUV in Coopers Plains, door placard 225/65R17 102H, two school seats, a dog, a weekend bag. The fronts are feathered inside. The rears have 4 millimetres. A chain has a $99 special in 225/65R17 98H. A local independent has a mid-range 102H for $40 more a corner and will align the car the same morning. The cheap special is not cheaper. It is a lower load index on a car that already lives full, and it will inherit a bent alignment. The independent is the grown-up quote.

Now change one fact: the car is a third car that does 2,000 kilometres a year to a boat ramp in the dry. The cheap special, if the date is fresh and the fitter will still write an invoice, can be the right rung. The article you are reading is how to tell those two Saturdays apart. The facts change. The method does not.

If you want a second human to look at a quote, that is what the write for us and contact pages are for — not to sell you a tyre, to tell you whether the sentence on the invoice is complete. Completeness is the product this publication actually sells.
